The nine living species are placed in a single genus, Heterodontus, in the family Heterodontidae. All are relatively small, with the largest species reaching just 1.65 metres(5.5 ft) in maximum length. They are bottom feeders in tropical and subtropical waters. The Heterodontiforms appear in the fossil record in the Early Jurassic, well before any of the other Galeomorphii, a group that includes all modern sharks except the dogfish and its relatives.

What these marine biologists discovered ● Long distance seasonal migrations of white sharks from the coast of California to the Hawaiian Islands. ● Migrations took about 23 days and other sharks went along similar paths defining a migration corridor. ● The visitation of white sharks to the waters surrounding the islands of Kauai, Maui, Lanai, Kahoolawe and Hawaii indicates these areas may be used for foraging.
